Chronic aortic dissection masquerading as systemic disease.

We report two cases of chronic aortic dissection whose prominent features were characterized by systemic symptoms (prolonged low grade fever, fatigue, weight loss) and biological acute phase response. In the first patient, a surgical repair of the descending thoracic aorta aneurysm was performed, allowing the disappearance of general manifestations, whereas spontaneous resolution occurred in the second case. Although aortic dissection is usually an acute and highly symptomatic event, the disorder can present--albeit rarely--as systemic illness and fever of unknown origin.
